Submission + - Up to 10% of CD-Rs fail within a few years! ( 1

crazyeyes writes: "Here's an interesting look at how fragile CD-Rs are :

In the past, hard disk drives were small (in capacity) and costly. To make up for the lack of affordable storage, many turned to CD-Rs. As it became common to store backups and personal pictures, videos, etc. on CD-Rs, the lifespan of these discs became a concern.

According to manufacturers, CD-Rs should last for decades. Some even quoted an upper limit of 120 years based on accelerated aging tests! That sure is a long time, isn't it? But will CD-Rs really last that long?

  • Did the writer do a read-back integrity check on the original archive? Even a more severe check, did the writer ever test the CD's in a different CD reader? If the data show no consistent pattern with age, maybe the problem isn't with the media at all.
